engine INFINITI QX50 2021 Owner's Guide

Be sure you do not put anything on top of the
autolight sensor located in the top side
O1of
the instrument panel. The autolight sensor
controls the autolight; if it is covered, the
autolight sensor reacts as if it is dark out and
the headlights will illuminate. If this occurs
while parked with the engine off and the ig-
nition switch placed in the ON position, your
vehicle's battery could become discharged.Headlight beam select
1To select the high beam function, rotate
the headlight control switch to the
position, then push the lever forward.
The high beam lights come on and the
light illuminates.
2Pull the lever back to select the low beam.
3Pulling and releasing the lever flashes the
headlight high beams on and off.
High Beam Assist
The High Beam Assist system will operate
when the vehicle is driven at speeds of ap-
proximately 25 mph (40 km/h) and above. If
an oncoming vehicle or leading vehicle ap-
pears in front of your vehicle when the head-
light high beam is on, the headlight will be
switched to the low beam automatically.
WARNING
• The High Beam Assist system is a conve-
nience but it is not a substitute for safe
driving operation. The driver should re-
main alert at all times, ensure safe driv-
ing practices and switch the high beams
and low beam manually when necessary.
• The high beam or low beam may not
switch automatically under the follow-
ing conditions. Switch the high beam and
low beam manually.
– During bad weather (rain, fog, snow,
wind, etc.).
– When a light source similar to a head-
light or tail light is in the vicinity of the
vehicle.
LIC2237LIC3820
Instruments and controls2-37

When the vehicle speed lowers to less than
approximately 16 mph (25 km/h), the head-
light uses the low beam.
To turn off the High Beam Assist system, turn
the headlight switch to the
position or
select the low beam position by placing the
lever in the neutral position.
Ambient image sensor maintenance
The ambient image sensorO1for the High
Beam Assist system is located in front of the
inside mirror. To maintain the proper opera-
tion of the High Beam Assist system and
prevent a system malfunction, be sure to ob-
serve the following:
• Always keep the windshield clean.
• Do not attach a sticker (including transpar- ent material) or install an accessory near
the ambient image sensor.
• Do not strike or damage the areas around the ambient image sensor. Do not touch the
sensor lens that is located on the ambient
image sensor. If the ambient image sensor is damaged due
to an accident, it is recommended that you
visit an INFINITI retailer.
Battery saver system
The battery saver system automatically turns
off the ignition after a period of time when
the ignition switch is left in the AUTO ACC or
ON position.
The battery saver system automatically turns
off the following lights after a period of time
when the ignition switch is placed in the OFF
position and the doors are closed:
• Headlights, when the headlight switch is in
the
orposition
• Interior lights, when left in the ON position
CAUTION
Even though the battery saver feature au-
tomatically turns off the headlights after a
period of time, you should turn the head-
light switch to the OFF position when the
engine is not running to avoid discharging
the vehicle battery.

Adaptive Front lighting System
(AFS) (if so equipped)
The Adaptive Front lighting System (AFS) will
automatically adjust the headlights (low
beam) toward the turning direction to im-
prove the driver’s view. When the headlight
switch is ON and the driver operates the
steering wheel in a turn, the AFS system will
be activated.
The AFS will operate:
• when the headlight switch is ON.
• when the shift lever is in any position otherthan P (Park) or R (Reverse).
• when the vehicle is driven at above 16 mph (25 km/h) for the left-side headlight. Note
that the right-side low beam headlight will
swivel but the left side will not swivel when
the vehicle is at a stop and the steering
wheel is turned. The vehicle must attain a
speed above 16 mph (25 km/h) before AFS
activates the left-side headlight.
AFS will also adjust the headlight to a proper
axis automatically, depending on the number
of occupants in the vehicle, the load the ve-
hicle is carrying and the road conditions. If the AFS OFF indicator blinks or the vehicle
information display shows an AFS system
error message after the ignition switch has
been pushed to the ON position, this may
indicate that the AFS is not functioning prop-
erly. Have the system checked. It is recom-
mended you visit an INFINITI retailer for this
service. When the engine is started, the head-
lights will vibrate to check the system condi-
tion. This is not a malfunction.
Automatic headlight aiming control
(if so equipped)
Your vehicle is equipped with an automatic
headlight levelling system. The headlight axis
is controlled automatically.
INFINITI recommends that you consult the
local regulations on the use of lights.
LED DAYTIME RUNNING LIGHTS
(DRL) SYSTEM
The LED portion of the headlights automati-
cally illuminate at 100% intensity when the
engine is started and the parking brake re-
leased. The LED Daytime Running Lights
(DRL) system operates with the headlight
switch in the OFF position. When you turn
the headlight switch to the
position for
full illumination, the LED lights switch from
LED DRL system to the park function. If the parking brake is applied before the
engine is started, the LED DRL system does
not illuminate. The LED DRL system illumi-
nates when the parking brake is released. The
LED DRL system will remain on until the
ignition switch is placed in the OFF position.
It is necessary at dusk to turn the headlight
switch on for interior controls and switches
to illuminate, as those remain off while the
switch is in the OFF position.
WARNING
When the LED DRL system is active, tail
lights on your vehicle are not on. It is nec-
essary at dusk to turn on your headlights.
Failure to do so could cause an accident
injuring yourself and others.

The HomeLink® Universal Transceiver pro-
vides a convenient way to consolidate the
functions of up to three individual hand-held
transmitters into one built-in device.
HomeLink® Universal Transceiver:
• Will operate most radio frequency devicessuch as garage doors, gates, home and
office lighting, entry door locks and security
systems.
• Is powered by your vehicle's battery. No separate batteries are required. If the vehi-
cle's battery is discharged or is discon-
nected, HomeLink® will retain all
programming.
When the HomeLink® Universal Transceiver
is programmed, retain the original transmit-
ter for future programming procedures (Ex-
ample: new vehicle purchases). Upon sale of
the vehicle, the programmed HomeLink®
Universal Transceiver buttons should be
erased for security purposes. For additional
information, see “Programming HomeLink®”
(P. 2-70).
WARNING
• Your vehicle's engine should be turned
off while programming the HomeLink®
Universal Transceiver. For additional in-
formation, see “Push-button ignition
switch” (P. 5-13). Do not breathe ex-
haust gases; they contain colorless and
odorless carbon monoxide. Carbon mon-
oxide is dangerous. It can cause uncon-
sciousness or death.
•
Do not use the HomeLink® Universal
Transceiver with any garage door opener
that lacks safety stop and reverse features
as required by federal safety standards.
(These standards became effective for
opener models manufactured after April 1,
1982.) A garage door opener which cannot
detect an object in the path of a closing
garage door and then automatically stop
and reverse does not meet current federal
safety standards. Using a garage door
opener without these features increases
the risk of serious injury or death.
• During the programming procedure your
garage door or security gate will open
and close (if the transmitter is within
range). Make sure that people or objects
are clear of the garage door, gate, etc.,
that you are programming.
PROGRAMMING HOMELINK®
If you have any questions or are having diffi-
culty programming your HomeLink® but-
tons, refer to the HomeLink® web site at:
www.homelink.com or call 1-800-355-3515.
NOTE:
Place the ignition switch in the ON position
(without starting the engine) when pro-
gramming HomeLink®. It is also recom-
mended that a new battery be placed in the
hand-held transmitter of the device being
programmed to HomeLink® for quicker pro-
gramming and accurate transmission of the
radio frequency.
